2-Chloromethyl-4-Methylquinazoline: Verified Supplier Guide

Description

Understanding the Demand Behind a “Verified Supplier” Search

Procurement teams searching for a verified and trusted supplier of 2-Chloromethyl-4-methylquinazoline (CAS 109113-72-6) are typically engaged in synthetic chemistry research programmes exploring quinazoline-based alkylation chemistry within DPP-4 inhibitor synthetic routes. This quinazoline-derived building block acts as a key alkylating intermediate, commonly applied to prepare advanced purine-dione intermediates such as 8-Bromo-7-(2-butyn-1-yl)-3,7-dihydro-3-methyl-1-[(4-methyl-2-quinazolinyl)methyl]-1H-purine-2,6-dione (CAS 853029-57-9), a widely studied intermediate for related synthetic sequences. As a niche intermediate positioned mid-way through multi-step synthetic workflows, buyers do not treat supplier selection as a simple commodity transaction. They require reliable batch consistency, complete technical documentation and scalable manufacturing capacity before establishing a long-term sourcing partnership.

This type of technical sourcing request is where Shandong Tianming Pharmaceutical Group, operating under the brand Tianming Pharmaceutical, delivers targeted support. As an R&D-focused enterprise specialising in fine chemical raw materials and synthetic intermediates with an integrated R&D-production model, the group supplies custom intermediates and fine chemicals to global chemistry research teams. Its portfolio of nitrogen heterocycle intermediates includes 2-Chloromethyl-4-methylquinazoline, alongside other building blocks for DPP-4 scaffold chemistry and SGLT2 inhibitor intermediate routes for Dapagliflozin and Empagliflozin research.

What “Trusted” Actually Means in Intermediate Sourcing

For a specialised quinazoline intermediate, trust is not a marketing slogan; it is built on verifiable operational capabilities. Three core criteria usually guide buyers to assess whether a supplier is suitable for advanced synthetic inputs:

Does the supplier maintain a certified quality management framework? Shandong Tianming Pharmaceutical Group’s production entities hold ISO9001 Quality Management System Certification — Shandong Sihuan Pharmaceutical Co., Ltd. (2025) and Guangxi Tianming Pharmaceutical Co., Ltd. (2024). The internal quality framework covers raw material incoming inspection, reaction parameter control, purification workflows and analytical testing standards.

Is the batch fully traceable? The group maintains full batch traceability covering raw material intake, reaction parameters, purification records and test data, with all production records archived for complete process chain visibility. This is highly relevant for intermediates such as 2-Chloromethyl-4-methylquinazoline, where downstream chemists need to reconcile every delivered lot with its full process history.

Is there independent recognition beyond self-reported claims? Group entities hold National High-Tech Enterprise status — Shandong Sihuan Pharmaceutical Co., Ltd. (2024), Shandong Tianming Pharmaceutical Technology Co., Ltd. (2025), and Guangxi Tianming Pharmaceutical Co., Ltd. (2023) — alongside provincial Gazelle Enterprise and Specialized and Innovative SME accreditations in Shandong and Guangxi.

Positioning Within the Heterocycle Intermediate Chain

Tianming Pharmaceutical’s heterocycle intermediate portfolio is structured around connected synthetic sequences rather than isolated single compounds. Alongside 2-Chloromethyl-4-methylquinazoline (CAS 109113-72-6), the catalogue includes structurally related building blocks for the same synthetic pathway, such as 8-Bromo-7-(2-butynyl)-3-methylxanthine (CAS 668616-98-4), 8-Bromo-3-methylxanthine (CAS 93703-24-3), and 3-Methylxanthine (CAS 1076-22-8). 

For customers sourcing 2-Chloromethyl-4-methylquinazoline, this means the same partner can also supply adjacent intermediates in the same synthetic sequence, reducing the coordination overhead of managing multiple vendors for one chemical route. This full-chain product matrix strategy is also adopted for the group’s flagship product families, including Orforglipron intermediate series and Sacubitril Valsartan Sodium related intermediates, with the core advantage of streamlining procurement from starting materials to advanced intermediates under one unified quality control system.

Documentation to Support Laboratory and Process Development

A supplier’s claim of being “verified” creates real value for buyers only when paired with technical documentation that supports internal lab and process development work. Shandong Tianming Pharmaceutical Group provides comprehensive technical documentation for its products, including Certificate of Analysis (COA), analytical test methods (MOA), impurity profile characterisation and stability study data. This documentation standard runs across the group’s product portfolio, with defined quality checkpoints for raw material receiving, in-process monitoring and finished material release.

Manufacturing Scale and Delivery Reliability

Supply stability is another core pillar of the “trusted supplier” evaluation, especially for customers scaling from lab-scale batches to larger pilot volumes. Shandong Tianming Pharmaceutical Group operates three coordinated production bases — Shandong Sihuan Pharmaceutical Co., Ltd. in Dezhou, Jining Tianming Pharmaceutical Co., Ltd. in Jining, and Guangxi Tianming Pharmaceutical Co., Ltd. in Hechi — with a combined fleet of over 160 reactor vessels and annual production capacity measured in hundreds of tons. In-stock items can be shipped within 7–15 working days after order confirmation, quality review, packaging and logistics arrangement; custom-made orders follow lead times determined by synthetic complexity, workshop scheduling and raw material availability, with expedited production scheduling available for urgent research projects.

This manufacturing capacity is backed by consistent R&D investment exceeding 10% of annual revenue. Two R&D centres in Jinan and Nanjing occupy more than 6,000 square meters of laboratory space, equipped with over RMB 40 million of professional analytical and testing instruments, including HPLC, gas chromatography, mass spectrometry, LC-MS and chiral analysis systems. This infrastructure supports independent process development across the intermediate portfolio, including quinazoline-based building blocks for DPP-4 scaffold chemistry.

Service Model for Procurement and R&D Teams

For buyers evaluating a new intermediate source, technical service support matters as much as the chemical itself. Shandong Tianming Pharmaceutical Group adopts a dual-support model: one dedicated account manager paired with a technical engineer for each customer. Routine technical enquiries are responded to with reference guidance within 2 hours, while complex technical challenges are addressed with a formal written report within 24 hours. The group’s CRM, ERP and BPM digital management systems streamline order handling, inventory tracking, production scheduling and customer coordination, enabling fast order confirmation and full international logistics services covering more than 30 countries and regions across South Asia, Southeast Asia, the Middle East, Central and South America, and Africa. Every shipment is covered by transport insurance, with compensation and replacement options available for quality damage caused during transit.

Summary

A search for a “verified, trusted supplier” of 2-Chloromethyl-4-methylquinazoline is essentially a search for suppliers with documented quality control systems, traceable production workflows and dependable delivery matched to the scale of your synthetic chemistry project. Shandong Tianming Pharmaceutical Group addresses these requirements through ISO9001-certified quality management frameworks, full batch traceability, complete technical documentation, and a service framework built around dedicated technical support — positioning Tianming Pharmaceutical as a reliable sourcing partner for teams working with DPP-4 scaffold intermediates and the broader heterocycle fine chemical supply chain.
